The model is the MR's
Sherman V with (of course) Italeri suspension and rubber
block tracks (I don't remember who is the donor kit). The
flail cradle, motor and other attachments are
scratchbuild. The chains are from bronze and were dipped
in selinioum acid to turn "black" (this is
a sort of liquid to paint real guns) and their ends
are from shotgun's bullets. The whole painting was done
with Vallejo Acrylics.
